I thought that we can keep this to avoid any confusion when porting to old
production kernel which uses ICE.

That old kernel w/ ICE doesn't have f2fs_post_read_required(), right?

I thought we backport features with order of the time fsverity/compression
feature was introduced, then f2fs_post_read_required() should be there
when we backport compression feature.

Thanks,
